Abstract

The present invention pertains to a refillable gas adsorption bed assembly having a box-like, generally rectangular frame The frame has a pair of oppositely disposed side members and a pair of oppositely disposed end members. There is a first and a second rectangular fine mesh screen mounted within the frame on opposite sides of a filler opening through one of the side members. The first and second prefilters are mounted within the frame. The first prefilter is disposed to one side of both screens and the second prefilter is disposed on the opposite side of both screens. The invention includes a housing for the gas adsorption bed assembly and a counterflow adsorber module formed by operably connecting the housings end-to-end.

Dependent claims

A refillable adsorption bed assembly, comprising:

a rigid, box-like, generally rectangular extruded metal frame having a pair of oppositely disposed side members and a pair of oppositely disposed end members, said members each having opposite ends;
said ends of said side and end members being connected at corners of said frame by fastening means and gasket means to prevent air flow therebetween;
first and second rectangular fine mesh screens mounted within said frame on opposite sides of a filler opening through one of said members, each said side screen having a peripheral edge;
first and second prefilters mounted within said frame, said first prefilter being disposed to one side of both said screens and said second prefilter being disposed on the opposite side of both said screens, each prefilter having a peripheral edge;
said members having a plurality of coplanar channels formed therein constructed and arranged to hold said screens and said prefilters;
means for sealably connecting said edges of said prefilters to said frame at a pair of spaced channels;
means including sealant means encapsulating said edges of said screens within a pair of spaced channels;
removable cover means for sealably covering said opening;
and
a bed of gas adsorption medium disposed in and filling the space between said screens and said members.

A housing for a gas adsorption bed assembly, said housing comprising;

a generally rectangular housing frame having a pair of oppositely disposed side members, said frame having an opening in at least one of said side members for receiving said gas adsorption bed assembly;
first and second internal partitions extending between two of said side members, said first partition being disposed within said frame proximate and parallel to a first side member to form an axially extending air inlet plenum therebetween, and said second partition being disposed within said frame parallel to said first partition and proximate and parallel to a second side member to form an axially extending air outlet plenum therebetween and an adsorption bed chamber between said first partition and said second partition;
sealing means for sealably receiving said gas adsorption bed assembly disposed within said adsorption bed chamber and dividing said gas adsorption bed chamber to form an inlet chamber on one axially disposed end of said sealing means and an outlet chamber on the opposite axially disposed end of said sealing means;
and
an oblique flow inlet into said inlet chamber through said first partition, and a flow outlet from said outlet chamber through said second partition, whereby air entering said axially extending inlet plenum can flow through said flow inlet, said inlet chamber, said gas adsorption bed assembly, said outlet chamber, and said flow outlet to said axially extending outlet plenum.
